Hello, I have put a Pinasco kit 225 ss on my PX 200 e with separate lubrication including 60 shaft.

i have found this :

The adjusting data, which Pinasco in its older catalogs published, are not valid any longer. The preignition should be stopped between 20 and 23° v.Ot (depending upon exhaust) and the Bedüsung the following values to be adapted: Luftkorrekturdüse: 190, mixing tube: BE3, main jet: 118-125, Nebendüse: 2,4-2,9 a hole should be bored into the air cleaner with these Bedüsung in no case, as this was to be read in old Pinascoanleitungen. This is only attached if a 160|er Luftkorrekturdüse is used! In addition, then the diameter of the drilling should not exceed 5mm. Note: Due to in series all right the high compression the Pinasco with superfuel should be operated. The compression should be taken back on use of a running exhaust system possibly be reduced, at least however preignition, and adapted the Bedüsung! "

Can someone please tell me what carburetor nozzles my si 24 with pump needed? thanks

I have literally no idea what most of that means, although I recognise some jet sizes. Do you have a link to the source? I've had better luck than google translate using this - https://www.deepl.com/translator

And welcome to MV!

So this cylinder is not good, 213 has worked well then came the 60 crankshaft and the new original 225 head from Italy and since then it runs badly. I have tried everything, it does not want to work, . I will better use an original cylinder on long stroke.

I have no experience of the 213 with a 60mm stroke, but I do use the Super Sport 225 kit with VRH head. I don't really know if the cylinders are different or if the stroke compensation is just in the head. However, when running with a normal (drilled) air filter, I use a pretty basic 160/BE3/130 and 55/150 in a 24/24 carb. When using a venturi, I have 160/BE2/150 and 60/160. It runs really well in both cases. I was running an original BGM BigBox but now use a Polini box.

Cylinders are identical, the difference are 2 different heads

Problem is: jerking or swallowing (sprayback with siproad) when
gas take-off in the partial load range, idle 45/140 and 160/be3 128, ignition timing 18°

Just to correct my typo, I use a 55/160 idle jet, not 55/150

According to the instructions, a 5mm hole is drilled over the idle jet ! Is that the solution to the problem? The main jet without drilling only the idle jet? Ask for your advice

I always drill two holes, one above each jet. The one above the main jet is bigger, probably 7mm in my case, but my memory could be bad.

Main jet actually fits, the idlejet area runs too fat, I'll try and report it with the hole 5mm over the idle and take the better 55/160

But not right, according to Pinasco, the mainjet meant, but this is not the problem, will not drill a hole, instead testing 48/160

Hi Zip

Couldyou post the other pages from the Pinasco manual please? I'd like to see what they say about timing, jetting, etc.[/quote]

Pilot jet is too small. Try a 55/100.
