I've sent emails to go USA with no response and all the distributors I call are out of stock. Friends at the track told me to just run the os speed carb on the MG because they are known for carb problems and the motor runs just as good with the speed carb.
Hi Loweredram, Nothing wrong with the MG carb at all. People are just not familiar with the long needle LSN tuning that's all. It's lack of knowledge on their part not the carb. Use the tuning guide and explanation on our web site (in the Tech Tips section at
http://www.go-racing.co.nz).
I have plenty of O Rings in stock here. I can airmail you some over (take around 5 - 7 working days from down here in New Zealand). Payment by PayPal. If your keen just PM me for details.
I think I might have emailed you the other day - re using the fuel tubing in the meantime for O Rings. It works a treat and lasts forever. Give it a go to get back on track.
The new OR-0023 nitrile O rings will not shred like the original choclate coloured ones in your MG. Once fitted they will last for ages. These were upgraded on all GO engines with the introduction of the GX Series.
