Hello looking for a bit of advice . Apologies if this has been covered

Purchased a GP last year fitted with an RT 195 , 28 dellortto with foam filter ,BGM clubman ( new fitted by me ) new BGM stator flywheel and CDI engine was rebuilt by previous owner who's had lambretta s for years . I'm getting very poor starting when cold if left for a few days it takes multiple kicks ,choke appear to be operating freely , carb was rebuilt ,new plugs etc . When scoot is used daily its not to bad ad performance is ok ,not a missile but quick enough to commute which is what I used it for. I have borrowed a compression test dial gauge because I'm beginning to think it may be a worn ring/cylinder issue I cant seem to find what the reading should be for 195cc in PSI ?

many thanks

Try it with the foam filter off and see how u get on

Thanks think I tried that last previously ill try again

Could be something as simple as plug gap, don't mean to insult your intelligence though.

What type of carb and size of choke jet ?

Compression tests are ok but probably better to strip down, have a look and take some measurements…...who knows what sort of life it's had

When was the last time you cleaned your filter and is it one that requires oiling?

Was the new Clubman a like-for-like replacement?
