"THE" most neglected component of every carb rebuild, always overlooked when chasing fuelling problems and almost never included in any carb rebuild kits.


Many classic and vintage MIKUNI choke plungers are now discontinued and no longer available new or pattern which leaves many machines unable to run as they should, if at all in severe cases.

I can now replace the worn out and previously irreparable choke seal on your original MIKUNI rubber/nitrile tipped starter plunger with a superior ethanol fuel resistant VITON  to restore correct choke function to your machine.

This will eliminate constant over fuelling from that source which causes rich running, sooty plugs, low mpg, power loss and idling problems amongst other issues that are the classic symptoms of degraded plunger seals compounded by the use of ethanol fuels on the original non compatible rubber and nitrile seal material.


The seals are replaced using my own exclusive one of a kind custom built tooling with a unique installation technique that is unavailable elsewhere and new full size VITON seats are inserted and retained as original without disturbing the factory rolled securing edge.


Please note that these seals are custom produced and were never a replaceable/serviceable part - UNTIL NOW..

Once done the results will restore the chokes full function and seal..

HAVE NO DOUBTS. 

If your carbs are running the original plungers they ARE leaking and affecting fuel economy at the very least. 

The latest recipient of new seats has reported improved starting, idling, crisper throttle response and an astounding 15 mpg increase just from this, an incredible improvement for such a simple repair that will pay for itself tenfold. 

( Results will vary in relation to the severity of the initial plunger wear of course )

Whether you wisely use my worldwide service or not i strongly recommend that the plungers are replaced or repaired BEFORE installing aftermarket carb repair kits or parts needlessly as it is highly likely that it's the leaking plungers causing the issues and not worn carb internals as many misinformed restorers are lead to believe.

Why compromise your expensive carb rebuild and your resto's fuelling and performance by not replacing the old leaking seals ?.


This is not an exchange service.

You will need to send me your own bare plungers ( with springs etc removed ) to re-seat which also keeps your resto as original as possible 
and you will receive back your own original plungers with new ethanol resistant VITON seats installed.

After you press buy it now i will message the details on where to send your plungers.

OVERSEAS BUYERS PLEASE NOTE.

When you send the plungers please be sure to send them marked as a GIFT and declare either zero or a low value under £39.
Anything over £39 attracts vat and customs which has to be paid before the package is released which will have to be added to your costs and we want to avoid and anything over £15 marked commercial suffers the same fate.
They should be sent to me bare with the springs etc removed and it's best to tape them to a piece of card to secure them and stop them rattling around.
Thanks.
