just done that tune up on my 1641 VW gunner trike here in Scotland. followed all your vids on the AN 6/8 oil cooler and fuel systems. aGreat work

[@JWClassicVW]

That's fantastic! Always liked trikes, happy to hear you're enjoying the channel. Appreciate the support!

[@type4revolutionstudio]

Yeah man the Solex perplex 😂😂😂😂❤

[@JWClassicVW]

Lol... so true, always tuned by ear.

[@roymacdonald1264]

Haha I commented on the battery before I watched the whole video . There is nothing wrong with your alternator. You started with a weak battery and drained it filling the bowl with gasoline . Sorry it just irks me seeing stuff like that !

[@DuckmanCycles]

30/31 is my favorite Solex... I'm actually gotten them running much better than a 34PICT on the same engine. 😁👍🏻

[@JWClassicVW]

They are a great carb!

[@tomasalvarez6040]

…somebody else on a chat said same thing. I hav 34 pict but considering 30/31. I assume u get roughly same power/performance? All i need is a different base plate adapter at the manifold i think.

[@johncollins5552]

Dont overthink engine tuning at idle, its another ball game to tune for performance under load which is what happens when driving and the cars body weight has to be pushed through the air

[@italo195]

What distributor did you pair the H30/31 with?

[@hylndrfan]

Works great with a 009 distributor. No flat spots

[@sylviescopazzo2445]

Thank you so much this video really helped. Can you tell me where the jet screw is?

[@OwhyeeVdub]

Sounds good!!

[@Rick11231948]

so far most people say 2 1/2 to 3 turns inital adjustment on big screw. but I can't find what the inital adjustment is for the little screw . Mine is a 1600 engine with rebuilt carb. It will run for about 30 seconds.

[@JWClassicVW]

It is the same initial adjust for both.

[@MetroSA-227]

Noticed you did not mention anything about the chock/CAM screw adjustment. A little more on the advance timing would have been nice.

[@vintage76vipergreenBeetle]

Nice information.

[@JWClassicVW]

Thanks brother!

[@hylndrfan]

What size o ring is used for the volume screw? Is it something out of a regular o ring kit?

[@JWClassicVW]

Not sure this is a new Carb, most rebuild kits will have all required o-rings.

[@JWClassicVW]

Good morning everyone!!

[@DuckmanCycles]

Good morning dude!

[@andykrishak982]

You do know that you used the wrong vacuum port for the distributor...You use the one by the carb flange for and SVDA

[@jimmywilkinson9190]

Thermostat In South Texas we don't need no stinking Thermostat !!!!!

[@JWClassicVW]

Truth!

[@ibrewster]

LOL, you pulled Goose in the garage and I thought, man that 40hp sounds badass. Then, you pan the camera to the engine stand 😂. Great video as usually! I'm just working out my H30/31 with an 009. I think I need a bigger main jet

[@danielbuchanan254]

Thats 1 thing I always mess up, is adjusting the carb. Every time I try, I get a flat spot so I have to pay someone to do it

[@davidrodriguez-rk4ee]

Say looked at your plug wires. They look off? Number 1 is in the back, then,4.3, 2 . Is this correct? I thought # 1 ,is in the front?

[@JWClassicVW]

They are correct

[@larrytucker1945]

Thank you for the videos. Which distributor are you running with the H30/31 PICT? My old DVDA is giving me lots of headaches. Does the H30/31 have enough vacuum for the advance? Thanks!

[@JWClassicVW]

SVDA... it's an electronic one I picked up from CIP1. Seems to advance fine under vacuum but I've read that the carb may not provide enough vacuum.

[@MikeMoose67]

Very thorough video I appreciate the help!!!

[@FarmerBrianTee]

Take the blindfold off, put in a wideband O2. Then you know exactly what it is doing.

[@JWClassicVW]

@@FarmerBrianTee nahh

[@FarmerBrianTee]

@@JWClassicVW Keep the mystery alive lol.

[@cd4222]

You seem to have disconnected the vacuum from the carburetor but did not plugged the vacuum at the carburetor to set the timing. This is like tuning the engine with a vacuum leak!

[@JWClassicVW]

That's true, good catch!

[@ThomasELeClair]

......That upper vacuum line is a ported line......no vacuum thru it at idle........Vacuum lines below the throttle plate see manifold vacuum at idle speeds.........

[@lb224]

What distributor are you running on this?

[@VWJawbreaker]

Sounds good 👍

[@JWClassicVW]

Thanks brother!
