so what one would best to fit?

[deanwilko]

ive got set one on both my engines and havent had anyprobs. ive taken the carbs off many a time and because there all rubber you can use them again

[mikey14sr]

Personally I'd go for the second type, the first ones look to easy to over tighten to the point where the rubbers are only providing a seal and not cutting down the vibrations.

[novait]

i was thinking set 2 but just taken the carbs of the manifold and they have set 1 type fitted.. what to do..?

[ck]

ive been using the ones in the first link with no problems at all... if anything they will give more movent for vibration dampening compared to the genuine misabs

[novait]

set one it is then.. cheers guys,.

[dumpycorsa]

I use the misab ones and haven't had any problems. As long as they seal and reduce vibrations they should work fine. If the carbs vibrate it can cause the fuel to foam and float problems

[SKoob]

set 2 for me, seem alot better than the set 1 that was on there

[Ash]

Had set one, just purchased set 2. Seem much better fitting wise, but haven't run the car yet.

I used the 2nd set on mine. just be careful to tighten the carbs down equally and do not over tighten. This book is worth a look if you're playing with carbs...

Got the same book, its very useful especially if you are looking to rebuild or service the carbs :thumb: Also check the guide in the articles on section on png about fitting a 1.6 and twin 40 carbs, they recommend the misab set

[novait]

thank you skoob ive just read the whole article about the twin carb set up and help so much cheers for that..:D

[Novasport]

I would go for the Misabs, but also do not forget the seciring nuts. I would recommend replacing the rubber bobbins that go on the manifold studs to mount the carbs.

[novait]

do you mean these washers?

[SKoob]

I've gone for the rubber dougnuts sandwidged in metal cup washers and then nylock nuts.

[novait]

Yes they are the ones, get some nylock nuts to stop them undoing as you don't tighten them up very much, need to leave a 1.5mm gap between the metal washers

[novait]

ok i will get a set of them as well.. any thing else what is the best throttle cables to use?

[SKoob]

have you already got a linkage?

[novait]

no ive got a single cable at the moment that come straght of the carbs at the moment

[crash_ndie]

get a double top linkage, i found wen i ran single cable the spring returns on the carbs put alot off straign on the cable. i got everythink i needed for them at demond tweeks bit pricy but they got it all in shop. dont know if you no but ull need a longer alternator adjustable belt tentioner too.

[chimp007_uk]

Hi Ben, Paul posted the pulley today... Apologies for that!

When you fit the misabs, don't overtighten them. you should be able to rock the carbs slightly :)

[novait]

ive already got a set of twin 40s on the car but there crappy solexs as i got them cheap been waiting for a good set of webers to come up and now ive got some..can you still use a double linkage with the irmisher airbox? the single cable that i use at the moment works ok..

[novait]

oh and cheers chris..
