VITTORAZI MOSTER 185 - Do you know your engine - Vittorazi Maintenance Day - A few secrets

[@angeredBee]

The most comprehensive descriptions of the Vitto version of the Walbro carbs that we use on our PPG’s. This is the first video I have seen where a Vitto rep provided technical training beyond the “what” to include the “why”. The info regarding mid-range, pop-off pressures and related should allow me to better maintain my A80. I really enjoy working on these engines, and the motorbike engines I have maintained over the years. It gives me an eye into the mind of the designers. More of this please, Giles? So glad I stumbled upon your channel.

Hi Brian and glad to see you back in the comments. It was a really good course and not just the normal "just do this" but why. The why who'll stop you damaging things. I do try and make information type videos but it's hard work getting good content.

[@angeredBee]

@@GolfFoxtrot22 100%, that last bit.

A good video to help people think about getting involved with routine maintenance and the need to do servicing on their engines. I do think that some treat their paramotor engine a bit like a lawnmower and not lay them up properly after a flying session and then expect them to work properly the next time they fly, the trouble is with these engines, fuel evaporates and leaves behind sticky oil and the oil also effects rubber part more when they are not in use. Most have the engine behind them so cannot see the exhaust smoke if it different and don’t have the instruments to tell them the cylinders are getting hot. I am not saying all neglect their engine but some just do not realise what they need to do so training sessions like this one really help open people's eyes.

[@GolfFoxtrot22]

Hi Algy, luckily the new Vittorazi manuals are very good and go al the way down to full engine rebuilds. If only people knew they existed.

[@flyingkub]

@@GolfFoxtrot22 There are a lot of people who might not have a torque wrench and also a lot who are worried they may do more harm then good.

[@GolfFoxtrot22]

A holed piston is pretty bad as well.

[@paulieb796]

Finally got round to watching this one. I learned a lot from the short snippets so the full day course has got to be worth it. Even though I don’t run a Moster engine, I am sure the principles would transfer to my engine. I’m sure there would be an audience for this course at Darley Moor.

[@GolfFoxtrot22]

It's amazing how such little pieces of information can help the everyday pilot.

[@InducedBank]

Great explanations! Wish we could get a session like that for the Rotax 912!

[@GolfFoxtrot22]

Hi Mike, it was a good course. There is a line maintenance course for the Rotax already run by CFS.

[@InducedBank]

@@GolfFoxtrot22 Cheers mate!

[@DanielJonesParamotor]

Invaluable corse Clive puts on. As Dom said, even if you aren’t going to do the maintenance, it’s worth spending the day learning how your machine works

[@GolfFoxtrot22]

Yes, I agree the course is completely worth the time, the low cost is also a bonus.

[@freebiker2765]

Hi Giles. Another valuable video, thanks. It would be a big mistake to let me loose on an engine! I’m the kind of guy that would create three new problems for every one he tried to solve! So, as my Moster 185 has just clocked up its first 25 hours, I’m relieved to be introduced to Clive’s operations. His detailed knowledge of the engine is very impressive. Cheers John

[@GolfFoxtrot22]

Hi John, I'm glad you found it useful. The full day would have given you so much more information but I tried to just give a flavour. The main 5hing, buy a torque wrench, you'll save yourself so many issues.

[@domHenderson1984]

Thanks for another good video Giles finally watched it, had no signal down RIAT, learned so much from this day would recommend it to anyone even if you don't have a vit all round good tips about how engines work and why they go wrong.

[@GolfFoxtrot22]

This is certainly very true.

[@vauxscott]

Good video Giles, definitly a course that should be high on people's list. Full of very useful hints ant tips, even for seasoned engineers!

[@GolfFoxtrot22]

Hi Scott, thank you. It's always good to learn new things. Clive has a very structured and logical way of proceeding any engine that he receives, and it Born out of lots of experience as well.

[@davidh7636]

Great video. I really wish someone would do course online for these engines. I would pay a good bit of money for access to good practices to maintain my engine. I know others would too.

[@GolfFoxtrot22]

HI David, I do see what you mean, but there is a lot of the day that are very hands on. But if we can learn from a KZbin video, then it can be online.

[@BrianTurboT]

Excellent ... I've learn't a bit more there ... I don't run a Moster myself, but some of this 'stuff' is pertinent to all machines :-)

[@GolfFoxtrot22]

Hi Brian, it certainly is and a good point. I tried to give a flavour of the course without give too much away.

[@ShortField]

I suppose there's something to say for a structured, accountable, overseen, maintenance regime even if we end up paying for it. Even in our GA little birds engine failure should be a rarity and one of the reasons why TBO's and required schedules are part of an aircrafts licence to fly. Even with low speeds and momentum having an engine go pop due to being badly looked after when climbing out over a lake or housing estate is still a fatal situation in a flex. Interesting video thanks Giles.

[@GolfFoxtrot22]

Hi Terry, even if it's a little knowledge to help prevent a messed up engine. Always appreciate a comment from you.

[@CessnaPilot99]

This was great! Any idea where an American can find a course like this here in the states? I wonder if the Aviator training school has an engine maintenance course

[@GolfFoxtrot22]

I'm not sure, but you could ask Aviator. Have you tried contacting Vittorazi?

[@GolfFoxtrot22]

@GrummanPilot99 how did your Channel name come about?

[@clivebunce2189]

Cracking :)

[@GolfFoxtrot22]

Hi Clive, glad you enjoyed it.

[@patrickmckowen2999]

Great vid -- points out why electric motors are far superior due to there simplicity - if only we had batteries that could be equivalent to gas range. Cheers

[@GolfFoxtrot22]

Hi Patrick, I completely agree, battery density is still the issue.

[@chriscasey4819]

Hi Giles great infomation on maintenance Also Want to ask you do you use CHT and EGT motomonitor to keep eye on temps I use CHT but do you have to have EGT or not Many thanks Chris

[@GolfFoxtrot22]

Hi Chris, I don't use a motormonitor as I have found them to be inaccurate. I run a cht and tacho. I can't fit an egt as it would damage the exhaust. I'm glad the video was useful.

[@chriscasey4819]

@@GolfFoxtrot22thanks Giles I didnt know about the inaccuracy how did you find this out I dont want to damage my engine with getting wrong feedback from my monitor Should I change it Thanks Chris

[@GolfFoxtrot22]

@@chriscasey4819 I've used them in comparison to my own and know how the temps that they are meant to be. A lady trashed her engine today by not reading the motormonitor. Also the RPM feed is way off.

[@edwalker2790]

Right, so if I need to do this procedure on my 185 out of the box, what has Vittorazi done to custom tune the carbs to get a smooth mid-range?

[@GolfFoxtrot22]

Ho Ed, the only thing they have done is blank off one of the low ilde ports. It's why I sent a year developing and testing my mod. The thing is, it needs to be carried out carefully and out of warranty.

[@falconron4217]

So what squish measurement for the 185. Some one said on one site I visited it was 1.5 mm? Is this correct?

[@GolfFoxtrot22]

Have you looked at the maintenance manual on the Vittorazi website, it gives the Squish.. Please don't take my figures as gospel but the minimum is 1.35.

[@edwalker2790]

What's the pop-off pressure psi?

[@GolfFoxtrot22]

HI Ed, if you look on the Vittorazi website and look uot the maintenance manuals it gives you the current pop off figures.
