Bit of a long post but bare with me!

A mate of mines just bought a HB 208 top end and all new bearings and seals etc for his P2 engine.The engine was stripped right down and Harry checked it all over,re-shimmed the gearbox and fitted a new conrod kit to his crank webs which he also trued for him.I rebuilt the engine for my mate,im quite competent as ive worked on them before (although im no expert!) but i fitted the bearings and seals properly and pulled the crank in very carefully with a puller,made sure piston was right way up etc etc so im confident the engine all went back together as it should.
Went round my mates today to fire it up,and after 10 kicks,nothing...dead.
Big fat spark,plenty of fuel getting through but no sign of life at all.The plug was getting soaked after a few kicks each time even after turning off fuel and clearing crankcase of it.Also it seemed to be chucking a large amount of fuel through the carb venturi from the crankcase.Much more than usual.I checked the stator,and it was on the IT mark as instructed by Harry and i also cleaned the carb jets and made sure the float was working ok...all good,but the engine keeps showing these symptoms.
Found out afterwards that prior to my arrival this morning,my mate had changed the stator pick up and instead of using the flywheel holding tool,he did up the flywheel nut with a big rubber hammer and bar!

Could this have twisted the crank causing all these issues as i cant think of anything else?

oops just miss red the post ..I always do the nut up that way never had any trouble that sounds like a carb problem

The carb was fine before when it was running standard and we blew all the jets out and checked float and it all looked good.Its chucking loads of fuel out carb venturi and flooding plug too,im just wondering if it is a twisted crank and the flywheel keyway is out and knocked the timing way out as well? He didnt use a holding tool,just whacked the nut tight

keep us informed pal best of luck

I had the same problem years ago ehem ide put the main seal in the wrong way round pulling loads of air in

Deffo put seal in right way with spring facing crank! He Rang Harry who said he doubt its the crank thats twisted, gonna try again tomorrow. May even set timing to the A mark again to see if it fires with a bit more advance then retard it afterwards hopefully

Update,

Set the timing back to the A mark,put in my warm plug from my P2 and second kick she struck up and ran sweet as a nut! Strange...
Let it warm up for 10 mins and put timing back to what Harry said.My mates well chuffed now,just 500 miles to run it in
