It could be the way the carb is fitted or accelerator cable to tight and pulling on the carb when you floor it as something not quite right if you are needed to replace it every couple of years. Have you tried different manufacturers/sellers of carb flanges? I’ve had 2 carb flanges split in 20 years...

Just looked at your post on the coolant flanges and if the picture is your engine then there is a bracket on the front of the air box, the airbox fixing does look to be at the very bottom of the U shaped bracket holder so it could be pulling on the rubber carb flange. If you are having to pull the c...

No sealant should be used or needed as the Oring should seal it and you’ve done the right thing with cleaning up the surface. I just went out to check which way the flange goes but forgot I changed mine for an early type metal flange but I think the flat bit goes on the bottom as that’s where the me...

Are you still using the original airbox? Is there a bracket on the front of it fitted to the rocker cover? I would check the rubber flange which the carb sits on again as they can easily split especially if you don’t have the bracket on the front or if the air box has been bent down to fit onto the ...

When I change my belt I check the tension by hand, turn the engine over by hand and then start the engine with the covers off and no alternator belt and run the engine for a minute, you can hear it whine like a super charger if to tight then when the engine has stopped check the tension again. Let u...

Looking online the gates tensioner look different to yours? https://www.ebay.co.uk/itm/314765460654?fits=Plat_Gen%3AMK+I%7CModel%3AGolf&hash=item49497bc4ae:g:NkMAAOSweQ1k1c1u&amdata=enc%3AAQAIAAAA0NgZGuPYyFBnl5adjihQ72h1yfYBAAH%2BoYHq0cfS1DA3Rw4PLiMD1RlP1BcMUyPgw6MQoMsrLSeCl%2B1P8GGjeutjT2ZT...

Errrr yes that’s not right, the middle should not come out of the tensioner and the belt should not wear like that after a short time. Maybe get them changed for new ones as the tensioner is faulty or try a different make? Tensioner and cam belts I’ve been using in both my cars for the last 20 years...

If the cambelt is too tight it will make a noise like you have a supercharger fitted and the noise changes with the engine revs.

Check that the belt is not catching on the covers.

The bottom bearing is plastic and can pushed in by hand, I left the tube in place when I replaced mine. Not done the top bearing yet. https://www.ebay.co.uk/itm/363560288775?epid=1716925762&hash=item54a5e1c207:g:91YAAOSwnp5hpmKP&amdata=enc%3AAQAIAAAA0OP84bDuorNcTUxzSiRKVR%2B6OGMOcoAh%2Bw6BbG...

Yes well done, seen the post and pictures on Facecloth

Yes that’s right, to use normal 95 RON now E10 unleaded fuel the timing needs to regarded by 6 degrees. A few years ago I did try normal 95 RON unleaded fuel in my Mk1 Golf GTi (DX engine) and retarded the timing for about a year and I found the engine a little flat to drive and I could not get a st...

If you remove the thermostat housing at the bottom of the water pump and it’s the plastic type buy a new plastic housing as they never seem to seal again. It looks like this and hopefully will come with a new rubber o ring. https://www.ebay.co.uk/itm/403444990274?hash=item5def320142:g:3yAAAOSwXcdj~j...

If you can use super unleaded petrol if your car is fuel injection they run better on a higher octane fuel. Super unleaded and normal unleaded petrol has had ethanol added (E5 so 5% ethanol) for many years, it’s just they have doubled the amount of ethanol in normal unleaded so it’s now E10, 10% eth...

Service kit I used but mine was on a 1.6 Mk1 , I did call them to check it was the right kit and they were very helpful so worth a phone call/email to check. https://fastroadcars.co.uk/store/index.php?route=product/product&path=60_74&product_id=325 Or they sell on eBay. https://www.ebay.co.u...

Yeah… it’s alive, well done on getting it going and at least now you know how the fuel injection system works.
