1981 hightop Aircooled vw t25 2 ltr CU on LPG

Just got my vanback from the garage after breaking down outside it! 3 days and rip of later had new ingition coil somthing to help it start! Anyway NOW (before went in was fine!) When acceletre hestales and jars and occaly back fires just not running rite. Have replaced HT leads as he recommend his now saying i need a new Dizzy cap and plugs could this be it? ( he has also said i need my carbs doing yet gasure did this not long ago! Also i need a new alternator but local garage approved this 2 weeks ago) and also tried fitting the wrong size dizzy cap! HELP! LOL

Is this when running on LPG or petrol, you don't specify?

Are thje plug gaps set properly for LPG?

How did it break down?
How was it going up till then?
What is the history of its conversion and running?
What does the grage know about LPG conversions?
etc...

They could have buggered about with so much we would be second guessing.. as requested, more info.. and what exactly have they replaced... (invoice)
could be a simple as they havent put the induction pipes back on properly etc etc...

Check they didn't knock the LPG lines.

There are two gold nuts on the line just before the Y junction. Check the arrows marked on by Gasure are both pointing in the same direction. Turn them with your fingers so they are both on the Y end and in line with the pipes.

Call Steve, he explains it alot better than me!

which garage did you use owduck,stokes full of wannabe mechanics who work at/start up a garage and havent got a clue.....i havent touched a petrol engine for 10 years or so...so i would'nt be very helpful.......sorry mate

Running on LPG as for Plug gaps sorry you lost me! It wouldn't start which is how it ended up in the garage! dead started ( garage diagnosed as ignition coil? thats all he replaced he says) Been jump starting in for week up till then and it rand Brill as always have got told have possible drain on battery but she starts fine now just runs like this! Conversion GAsure no probs brill runner... Told him it was LPG and not touch anything to do with it as it was in warrenty with someone else he said no problem..

I will try to check them valve things 2moro when its lighter and see how that goes too. thanks for all your help. Yes sunny stoke i no a few good garages however it broke down by one near me and was desprete! Turns out the mechanic has apoligised cars arn't easy and his going thru a messy divorce! thanks for this guys! Don't like to be a typical women! but! lol

What I was asking, mainly, was is it running badly on petrol or LPG?

Was the starting problem just an electrric starter problem, say a flat battery so the engine wouldn't turn over on the key?

So what is your next step then, other than checking those valvy things

Trouble with swopping/replacing rather than objective diagnosis is that every time you replace or alter something you are liable to cause the odd problem along the way so the vehicle finishes up more busted than before. Clever as I am I spent several hundreds of pounds sorting out my obviously decrepit ignition system before discovering I had an intermittent problem with my ECU. Sad thing is my ex Specialist Cars mechanic mate helped me all along the way! You need a tame VW man who aint on an hourly rate.
Good luck with it anyway.

... and?

Check the plug leads are on the right way ..... 1 and 2 (right side when viewed from't rear) cross over each other, t'others don't.
