Hello my name is Michael and I live in France.
I have a RANSOMES MG6 with a Drayton engine type 34 (ignition with a cotton wick).
In France nobody succeeded in resolving my problem, I hope I will have more chance with English experts.
Last year my crawler started very well till I decided to check all the differents fonctions of the MG6
• Setting of the injector by a diesel mechanic.
• Rehabilitation of two brakes.
• Replacement of gazoil supply line.
• Replacement of the gazoil return pipe to the tank.
• Filling the tank with white gazoil.
• Taring the air intake valve.
• Replacement head gasket (purchase at Neil JARRETT), assembly with aviation paste and tightening the 4 nuts at 41N.m.
After bleeding air, I made my first starting tests. I completely close the air. I put the gazoil arrival in mid position (via cable). I pull the priming lever.
Result: After several ignition with cotton wick I created for 10 seconds, a series of explosions. (with a beautiful white smoke). So I conclude that there is a good air tightness at the cylinder head gasket.
Yesterday I decided to adjust the single valve with a hold of 0,15mm. For that, I introduced a wood stem into the hole (this one for the cotton wick) in order to identify the high died point TDC, then I have to regulate a 0,15 mm play on the level of the closed valve.
Result: After I inserted a new cotton wick I do not succeed any more to turn the crank (there is like a blocking, a hard point).
Could you advise me ? Did I well identify the TDC ?
Is my starting procedure is correct?
How to carry out the good adjustment of the valve?
Thank you by advance for your comments and ideas.
