Rob :D --- End quote --- I don,t think it is your comp rob , I have a similar problem on our m/c , When I want to machine pockets equally spaced on a given pcd , rectangle pockets no problem , If I want round pockets ,sometimes I have to datum shift a fraction of a degree ,( .002 / .oo4 of a degree) after the first pocket , if I don’t it will miss some of the pockets out , we've put it down to an Anomaly in the software, :offtopic: apologies for going of topic in your thread , enjoying the thread so far rob , some 1st class machining ,, be proud to put my name to any of your jobs , looking forward to more of the same from you ,,,,,,cheers ,,,, jeff |

On teh vertical I'm doing at teh moment it has a fuel pump so its no an issue. Jason --- End quote --- Hi Jason If i have a hight problem ,,,,,, i will fit a lift pump :dremel: ,,,,,, loads of room on the carb side of the engine for a small pump :med: Rob |
| Jasonb:
You will probably need a different carb as the pump will still be pumping while the engine is missing and will flood the carb. I've just posted some pics of the pump and plumbing for my IHC here Jason |
