What's that chuffin' noise?

After another break last weekend, and all day wasted trying to fix the car doors on the 75, I thought I might just see if the old girl would start. She did, no problems at all. I let her run for a while to get nice and warm. For some reason, there was no green leaking although it was nearly dark so I couldn't see a great deal in the engine bay. I let off a bit of choke and it still ran ... bit more ... excellent! She is ticking over beautifully. Higher revs always result in backfires but it is soundin better than ever. Sounds a little fast though so I need to get the tacho going to make sure of the tickover speed.

Due to the darkness, I killed the engine. It was then that I decided to have another go just to see. What's that chuffin' noise? It sounds like the fuel pump is about to explode! So why has that suddenly decided to play up?!

Catch Up ii

Alright alright, I am getting slacker with the updates so this is for Anonymous (Paul?). Thus, latest news is that due to the cold and my ever increasing lack of interest, I have rarely been in the garage other than to get the odd box of Christmas lager. Two weekends ago, it started nearly first time but was still spluttering very badly and shooting flame up Rosemary Road at any more than 3000 revs.

It was at this point that I armed myself with downloaded images of SU carbs, a scredriver and a Simon. We twiddled the mixture screw right down until the engine died and twiddled a quarter turn until it started again. The plugs were removed and cleaned for the 86th time.

The result was a much better sounding engine that when slightly warm (can't tell how warm as none of the instruments work), ticked over nicely at about 800rpm (probably as the tacho don't work either). At low revs all is well. At higher revs, you still don't want to be standing behind it, unless you have a marshmallow on a fork.

Next? If it starts and runs ok this weekend, it will be insurance and MOT time. The pre MOT To Do List includes: drivers seat screwed down properly, dials working, oil flush and change. The post MOT To Do List will probably be very long.

Oh, and I still have a green leak. F knows where that is coming from. Looks like it's the port on the head. So does that mean a buggered manifold gasket that I didn't change? Or something more serious?
