  1. Car starts fine now but I am having a problem with petrol leaking at the carbs. 

    I have tightened the banjo bolts as tight as I can and the float chamber bolts underneath seem to be OK now but needed excessive  tightening.

    However I have petrol leaking past the jets. I have used the 2 viton o rings in place of each Cork seal to make the seals ethanol proof but they seem to be leaking and these can't be tightened up.

    Anyone else have this problem with H4 carbs.

    Thanks Eddie 

  2. Keith,

    It might have been the petrol. I've read that the ethanol attracts water and maybe I had some at the bottom of the tank. The car had become more difficult to start over the winter and I didn't take it for a run so the petrol at the bottom of the tank  wasn't getting used.

    Just tried it today and it started first time and I haven’t adjusted anything from when it wouldn't start so hopefully everything is OK now.

  3. Started today with Easy Start.  Doesn't sound too bad considering I have not adjusted the carbs yet. Still a mystery why It wasn't even trying to start before using Easy Start. It now starts better than ever before.

    Thanks everyone for the advice.

  4. Thanks for the replies

    Definitely petrol in bowls, I  had a few leaks and was surprised how tight everything needed to be to stop leaks,  especially the banjo bolts . Thought I had centred jets OK but now one piston drops with a clunk and the other slightly quieter.

    However plugs don't seem to be very wet after cranking many times.

    I will try some easy start tomorrow to see if I  can get it going.

    Thanks again Eddie 

  5. Have completed the refurb of the H4 carbs and fitted them but the car won't  start.

    I haven't touched the ignition at all.

    Timing checked OK,spark at each plug, firing order correct, plenty of petrol getting to carbs( I had trouble with leaks at the banjo bolts) but car won't start. Pistons move freely in the carbs,have swopped the plugs,still won't start , not even firing.

    Have left the battery on charge but stumped by this.

    Any suggestions?

    Thanks Eddie 

  6. Maybe I am being over cautious.

    The new spindle measures 0.311 and an 8mm drill measures 0.314 with my old micrometer. 

    The drill will enter the body at both ends but will not go through so I have less than 0.003 clearance which is probably acceptable. The old spindle is down to 0.304 in worst place.

    Thanks Eddie 

  7. How are the durable dot studs fastened to the ends of the screen capping?

    I have bought the studs and self tapping screws in Moss parts catalogue. The self tappers don't look like self tappers and the aluminium capping doesn't look strong enough to take a self tapper. Do I have to drill a hole in the windscreen frame?

    Thanks Eddie 

     

  8. We learn something every day. Trouble is I tend to forget it the next day.

    It is amazing what knowledge there is from the people on this forum.

    I will try to do a blowdown test to see if I can get a better idea of the engine condition.

    I have been offered a saloon 2.5 engine , supposedly in good condition, for little money and wonder if that would fit without too much work.

    Thanks Eddie 

     

  9. For info the car is a TR250.  Engine is not original but I have been informed that the number is correct for the TR250. Starter is new but not high torque  Battery is new. Car starts and ticks over fine so I a  sure timing etc is not far out. Head came loose with the car but is the American style with narrow manifold spacing. It looked like it had come from a machine shop not  diy refurb.

    I have just checked the compression on my mg. It was a steady 75/76. This is an 1800 3 bearing engine with less than a 1000 miles on the clock and a Peter Burgess econotune head which is probably slightly higher compression than normal. (know I am spending too much time in the garage and not enough  driving).

    So TR readings might not be as disastrous as first appeared .

    From memory the bores didn't  look bad before I put the head on.  If the rings have been replaced is there a running in time for them to achieve  a good seal?

    Many thanks for all the replies.

    Eddie
