me dad runs a fast road anglia with a 1690 xflow. we just changed the ignition over to the mk2 fessy one (does away with the points) and reset the plug gaps and timing appropriately and it goes like fook now, however once a certain temp is reached we get fuel vapourisation cos the inlet manifold gets far too hot. so we just cant start her for ages!!!! the fan were runnin is an electrical one that runs off a switch at our discretion and not constant on the pulley as per original xflow design. we cant fit the fan between block and rad so it sits in front of rad and sucks air out. its so tight in the engine bay that were really runnin out of ideas as to keepin her cool!!! any advice from fellow oldskoolers out there would be really really really appreciated. hope this makes sense to someone!!!!!

 

Where is it getting vapor locked in the lines or in the carb. Put a electric fuel pump on it. That should cure it.

 

Could you not have used a fan that blows the air rather than pulls it?

Does the car crank/turn over O.K. on the starter or does it seem to stop turning when trying to crank it over?

 

I'm with ZVH you should get a pushing fan.

 

whitney- vapour in carb, u can see it happening in there. yeah we thought bout fittin a facet or summit similar but the worry is it could still be hapenin as inlet will still be so hot!!

zvh- yeah starter is all good, dunno if we can get fan to fit in blowing direction, will have to try. its hard to explain!!! thanks for helpin guys....keep it cumin!!

 

You can't simply turn the + - to the fan to change direction, you have to buy a fan specifically for blowing.

 

If it's in the carb you should get a phenolic spacer for the carb or just build one out of 1/4 inch plastic or wood. I know it sounds bodgy but the wood is acually better for keeping the heat away. BTW do you run coolant through your intake?
